Bob Azzi, Sprint's senior vice president for Network, said in a statement: "Customers report they are already finding a 4G LTE signal in these places, and we look forward to providing even more reliable access to the data they need with our official launches."

Sprint initially hitched its post to Clearwire's 4G WiMax service before hopping onto the LTE bandwagon this past July. Since then, the company has rolled out 4G LTE to a total of 67 markets. Sprint still lags far behind Verizon and AT&T, but it is ahead of T-Mobile, which doesn't yet offer LTE coverage and instead relies on its 4G HSPA+ network.
